  abstract={A long-standing controversy is whether leveraged buyouts (LBOs) relieve managers from short-term pressures from public shareholders, or whether LBO funds themselves sacrifice long-term growth to boost short-term performance. We examine one form of long-run activity, namely, investments in innovation as measured by patenting activity. Based on 472 LBO transactions, we find no evidence that LBOs sacrifice long-term investments. LBO firm patents are more cited (a proxy for economic importance), show no shifts in the fundamental nature of the research, and become more concentrated in important areas of companies' innovative portfolios.},
  filename={Lerner et al (2011) - Private equity and long run investment the case of innovation}
}

Finds that patents private equity backed firms applied for in the years after the investment are more frequently cited, showing no deterioration in patent orginality and generality. The level of patenting does not appear to consistently change, and the firms' patent portfolios become more focused in the years after the private equity investments. The areas where the firms concentrate their patenting after the private equity investment, and the historical strengths of the firm, tend to be the areas where the increase in patent impact is particularly great.

Data:

Capital IQ data, Dealogic data, SDC VentureXpert, and compilations of news stories to identify private equity transactions, their characteristics, and the nature of their exits. 472 LBO transactions between jan 1980 and december 2005.

Used Harvard business school patent database, which contains U.S. patent and trademark office electronic records through may 2007. HBS patent database was researched and cleaned up version of USPTO database.

Final sample consists of 6398 patents from 472 firms granted from 1984 through may 2007.

Buyouts of corporate divisions are most common, followed by private-to-private deals (investments in independent unquoted entities), secondary deals (firms that were already owned by another private equity investor), then public-to-private deals

Robustness Checks:

Concern one: Private equity investments for which there was already an existing investor, patents may be double-counted. Employs these patents only the first time they appear then drops them. Results are little changed
Concern two: Only measures citation count during the 3 years after the award. Using a longer window increases accuracy but decreases sample size. Repeats the analysis through the end of the second calendar year after the patent grant and after the fourth year and finds that results are quantitatively similar.
Concert three: In divisional buyouts corporate parents may retain best patents and only give low quality patents to the PE backed division. This may lead to an apparent increase in quality in the patents applied for after the award. Addresses this issue by using the longer window for patents above and by rerunning cross tabulations and regressions with divisional buyouts excluded from the sample. Key results are little changed by this shift.

Variables:

secondary exit - an LBO backed firm subsequently sold to another private equity fund
IPO - an lbo backed firm subsequently going public
trade sale - an lbo backed firm sbusequently being acquired by a strategic buyer
bankruptcy - an lbo backed firm subsequently filing for bankruptcy
event year - indicator variables that equal one for the given year in event time (the base year is year 0)
post - an indicator variable that equals one for event years 1 and forward
post plus one - an indicator variable that equals one for event years 2 and forward
share of firm's preinvestment patents in class - the fraction of the firms' pretransaction patents that are in the same industry class
change in firm's patents in class - an indicator for whether the difference in the share of patents in the class between the pre- and posttransaction periods is positive
post x share - an interaction between post and share of firm's pre-investment patents in class
post x change - an interaction between post and change in firm's patents in class

   abstract={Leveraged buyouts (LBOs) have created much controversy in the literature, centering on their potential effect on a company's ability to innovate, engage in new ventures, and support entrepreneurial projects. Some believe that post-LBO debt reduces the financial resources available for entrepreneurial activities. Conversely, others argue that, despite the burden of debt, some LBOs provide executives with an opportunity to innovate and take risks (Malone 1989). However, past studies have focused primarily on changes in R&D spending and ignored other corporate entrepreneurship (CE) activities a firm might pursue. Additionally, these studies have not documented the changes in CE after a management-led LBO. Thus, past studies offer only a snapshot of the effect of LBOs on CE. Finally, earlier studies did not directly examine the association between changes in entrepreneurial activities after the LBO and changes in performance.},
   filename={Zahra (2015) - Corporate Entrepreneurship and Financial Performance The Case of Management Leveraged Buyouts}
 }

Results from this study suggest that a company's commitment to corporate entrepreneurship (measured through innovation and venturing) increase after an LBO. Results also show that post-LBO changes in corporate entrepreneurship are associated with, or accompanied by concurrent changes in company performance.

Data: 47 LBO firms, data from annual reports, business week, compustat, dun's million dollar, interviews, commerce department publications, forbes, funk and scott, fortune, wall street journal

Data was measured with the following variables:

Innovation
- R&D Spending
- R&D Focus (types, i.e. basic, applied, or developmental)
- radical product innovation
- product modification
- commercialization
- use of external R&D sources
- improving R&D staff quality
- increasing R&D staff size

Venturing
- percent of revenue from new businesses or industries which showed a company's ability to expand operations to achieve profitability
- the number of new businesses the company has entered that showed an increase in the emphasis on redefining the company's business concept
- the number of new market segments served by the company that gauged the increase in the scope of operations

company performance
- employee productivity
- sales-to-beginning assets, shows the company's ability to use its assets effectively
- return on investment
- earnings before interest and tax to assets ratio

control variables
- technological opportunities, size, age, and level of debt

   abstract={The paper analyses the impact of private equity (PE) backed leveraged buyouts (LBOs) on innovation output (patenting). Using a sample of 407 UK deals we find that LBOs have a positive causal effect on patent stock and quality-adjusted patent stock. Our results imply a 6% increase in quality-adjusted patent stock three years after the deal. The increase in innovation activity is concentrated among private-to-private transactions with a 14% increase in the quality-adjusted patent stock. Further analysis supports the argument that PE firms facilitate the relaxation of financial constraints. We also rule out alternative explanations for portfolio firms’ higher patenting activity. Our findings suggest that PE firms do not promote short-term cost-cutting at the expense of entrepreneurial investment opportunities with a long-term payoff.},
   filename={Amess et al (2015) - The Impact of Private Equity on Firms Innovation Activity}
 }

The results show that PE-backed LBOs have a positive causal effect on both patenting and quality-adjusted patents measured by forward citations. This implies an increase in innovation activity rather than an increase in strategic patenting. The impact is predominantly driven by private to private LBO transactions. The findings are consistent with PE firm involvement relaxing financial constraints in firms, facilitating their investment in innovation activity.

Data:

Sources are the Center for Management Buyout Research, FAME, and PATSTAT. Data on PE firms and portfolio firms comes from CMBOR, which provides info on lbo deals. The FAME database provides financial and accounting data for UK firms. PATSTAT provides data on patent applications and citations in Europe. LBOs take place between 1998 and 2005. 407 UK deals.

outcome variables
- patent applications
- patent applications weighted by forward citations i.e. changes in innovation stocks over time

conditioning variables
- firm size (the log of sales)
- labour productivity (the log of sales per employee)
- exporting (an exporter dummy)
- skill intensity (the log of the average wage)
- debt (liabilities divided by equity, i.e. leverage)
- profitability (profit divided by sales)
- age (log firm age)

After such companies received private equity backing, the patents they applied for received more frequent citations than patents awarded before the involvement of PE firms. Companies acquired by private equity also show no sign of deterioration in patent “originality” and “generality,” which have been shown to be fairly reliable indicators of the fundamental nature of the research. And while there is no clear pattern of change in the level of patenting activity, corporate patent portfolios become more focused in the years after the private equity investments. The increases in our measure of patent “impact” are greatest in the areas that constitute the companies' historical core strengths. These findings are likely to prove increasingly important as private equity continues its incursions into growth areas of the economy.},

Contrasting 175 LBO targets on the French market with an industry-matched comparison group, we first run univariate analysis and then multivariate analysis(logit regression). Beyond the underscoring of the LBO targets‟ financial features, we conclude that subdividing our sample according to the vendor and bidder type is beneficial. We thus notice that the so-called outperformance of LBO targets prior to the deal hides in fact different cases.}

Confirms LBO targets are less indebted and possess relatively more liquid assets than their industry counterparts. Contrary to former findings, LBO's business risk also seems to be higher than for non-LBO firms prior to the deal. Also corroborates or disagrees with some dozen other hypotheses.

They do not show signs of having excess free cash flows but there is some evidence of lower growth opportunities. We do not find that firms going private experience a greater threat of hostile acquisition. The results are therefore consistent with incentive and monitoring explanations of going private.

Considers public to private transitions of non-financial firms in UK (1998-2000) compared to matched controls (by size and industry). This includes management buyouts as well as LBOs. Finds the following relations:

US and UK PTPs have different causes, probably due to tax differences with respect to debt versus equity financing.
Identifies three hypotheses: market for corporate control, incentive alignment, and monitoring.
- Market for corporate control: Free cash control, threat of takeover insignificant
- Incentive alignment, monitoring: Higher CEO shareholdings, higher institutional shareholdings, more duality, lower Q ratios significantly related to higher chance of PTP

percentage independent directors
duality of CEO and chairman
percentage of shares held by CEO

       abstract = {This paper investigates the determinants of leveraged buyout activity by comparing firms that have implemented leveraged buyouts to those that have not. Consistent with the free cash flow theory, the authors find that firms that initiate leveraged buyouts can be characterized as having a combination of unfavorable investment opportunities (low Tobin's q) and relatively high cash flow. Leveraged buyout firms also tend to be more diversified than firms that do not undertake leveraged buyouts. In addition, firms with high expected costs of financial distress (e.g, those with high research and development expenditures) are less likely to do leveraged buyouts.},

By August 1990, 62% of the LBOs are privately owned, 14% are independent public companies, and 24% are owned by other public companies. The percentage of LBOs returning to public ownership increases over time, with LBOs remaining private for a median time of 6.82 years. The majority of LBOs, therefore, are neither short-lived nor permanent. The moderate fraction of LBO assets owned by other companies implies that asset sales play a role, but are not the primary motivating force in LBO transactions.}

Our results indicate that not all LBO firms eventually will reverse, i.e. the net benefits of private status for some firms appear to be permanent.

       abstract = {Because of increasing levels of competition and decreasing product life cycles, a firm's ability to generate a continuous stream of innovations may be more important than ever in allowing a firm to improve profitability and maintain competitive advantage This paper investigates several issues that are central to an examination of the innovation productivity in a firm. First, the relationship between a firm's commitment to research and development and its innovative outcomes is examined. Two innovative outcomes are analyzed: (1) invention, which focuses on the development of new ideas; and (2) innovation, the development of commercially viable products or services from creative ideas. Invention is measured by the number of patents granted, and innovation is assessed by the number of new product announcements. Second, because many inventions ultimately result in marketable innovations and because patents may provide protection for new products, the relationship between patents and product announcements is also investigated. Finally, the ability of a firm to benefit from its inventions and innovations is studied by examining their separate effects on firm performance, measured as return on assets (ROA) and sales growth. Drawing from a sample of 272 firms in 35 industries over 19 years, the results from a model of simultaneous equations provided support for some of the hypotheses, but several other surprising findings were found. As expected, R\&D spending was positively related to patents. This finding is consistent with others who argue that internal research capabilities, particularly those with a strong basic research component, is key to enabling a firm to generate creative outputs. More surprising was the finding of increasing returns to scale to R\&D spending. While this contradicts much of the existing research, it is consistent with economic arguments for the advantages of scale in innovation. Also interesting is the finding that, while a significant curvilinear relationship exists between R\&D spending and product announcements, it is not the predicted inverse-U but instead a U-shaped relationship. Consistent with previous work, product announcements were found to be positively related to both performance measures. A negative relationship was found between patents and both ROA and sales growth. While these findings were unexpected, they are intriguing and call into question the value of patents as protection mechanisms. In addition, these results may be resulting from the rise of strategic patenting, where an increasing number of firms are using patents as strategic weapons. As expected, a positive relationship was found between patents and new product announcements.},

Hitt et al argue that acquisitions are substitutes for R&D/patents and other investments. We should keep this in mind when using these as regressors in the same equation.

This paper studies the innovative performance of a large international sample of nearly 1200 companies in four high-tech industries, using a variety of indicators. These indicators range from R\&D inputs, patent counts and patent citations to new product announcements. The study establishes that a composite construct based on these four indicators clearly catches a latent variable 'innovative performance'. However, our findings also suggest that the statistical overlap between these indicators is that strong that future research might also consider using any of these indicators to measure the innovative performance of companies in high-tech industries.

Instead, variation in economy-wide credit conditions is the main determinant of leverage in buyouts. Higher deal leverage is associated with higher transaction prices and lower buyout fund returns, suggesting that acquirers overpay when access to credit is easier.},

The absolute size of the acquired knowledge base only has a positive effect during the first couple of years after which the effect turns around and we see a negative effect on the innovative performance of the acquiring firm. The relatedness between the acquired and acquiring firms’ knowledge bases has a curvilinear impact on the acquiring firm's innovative performance.

       abstract = {Buyouts have been described as a specific form of financial acquisition that leads to potentially substantial, but also highly volatile returns to equity investors. Previous research has illustrated a number of mechanisms through which buyouts cause increases or decreases in company value. Besides the traditional mechanisms like improved governance or incentive systems, more innovative and entrepreneurial levers like increasing strategic distinctiveness and mentoring are examined. While it is important to understand the performance impact of each of these levers individually, we are still missing a comprehensive framework that captures the full complexity of the buyout value generation process and recognizes interdependences between various factors. In this paper, we develop a three-dimensional conceptual framework for value generation in buyouts that categorizes and links the different levers of buyouts value generation. This framework provides the basis to take a look beyond individual value levers and sheds light on the underlying strategic logic of buyouts. We then review the literature on buyouts and categorize previously identified levers of value generation according to our framework. At the same time, we identify a number of levers that have received little attention in the academic literature so far or still lack convincing empirical support for their performance impact. Building upon this assessment of the status quo in research in buyout value generation, we outline an agenda for future research.},
